Connecting Georgia seafood producers to consumers during the coronavirus pandemic

by Emily Kenworthy

As farmers and food distributors struggle to get their products into the hands of consumers, UGA Marine Extension and Georgia Sea Grant has teamed up with UGA Cooperative Extension and the Georgia Department of Agriculture to generate business for the seafood industry.

The Ag Products Connection, a partnership between UGA Extension and the state agriculture department’s Georgia Grown program, is designed to connect farmers and seafood producers with customers around the state looking to source local food products. Businesses can sign up to have their companies promoted through the online platform, which lists local businesses by county.

“The resource was developed for producers who had a glut of product. Some were selling to school systems or restaurants, but now they don’t have those avenues of customers,” said Tori Stivers, seafood and marketing specialist for Marine Extension and Georgia Sea Grant. “With this program, they can market directly to consumers who can serve as new source of revenue for them.”

Stivers is working with fisheries specialists in UGA Marine Extension and Georgia Sea Grant to promote the resource to seafood professionals, many based on the coast, who are dealing with a surplus of product during the pandemic. She recently shared the resource with a list of more than 150 seafood wholesalers in Georgia, encouraging them to sign up.

“My hope is that it provides some income to those who have seen their business drop during this time so they can keep as many employees on the payroll as possible,” Stivers said. “If they can supplement their business by going directly to consumers, it might help them stay open.”

Some seafood businesses, like Southside Shellfish in Savannah, have already signed up for the program.

“We’ve seen a decline in clientele, but we’re still here and we’re still operating,” said Hope Meeks, owner of Southside Shellfish. “That’s why I think this resource will be so good because people keep calling and asking if we’re open, which we are.”

Meeks’ business has been involved in commercial crabbing since 1991. The retail business began in 2007, with the opening of a market in south Savannah. In addition to local blue crabs, they sell black sea bass, snapper, flounder and other seafood native to the east coast.

“I’m hoping that this will bring in our regular customers as maybe new customers that don’t already know we’re here,” she said. “We have raw and cooked seafood, so for those who are skeptical about eating out, this is great way for people to source shellfish and fish products you can catch in our area.”

Georgia’s seafood producers and wholesalers who are keeping regular hours, providing curbside pickup, home delivery or e-commerce sales during the COVID-19 crisis can join the program by visiting the Georgia Grown Ag-Products Industry Promotion  or Georgia Grown E-Commerce Promotion pages and filling out forms that will add their information to the statewide database of producers that is being shared with consumers and buyers.

Consumers can find seafood resources listed by county HERE.

Georgia Grown — a state membership program designed to help agribusinesses thrive by bringing producers, processors, suppliers, distributors, retailers, agritourism and consumers together — is waiving all membership fees for the service until July to help producers affected by the crisis.

Marine scientists map fish habitats

by Alan Flurry

Beyond the barrier islands of coastal Georgia, the continental shelf extends gradually eastward for almost 80 miles to the Gulf Stream. This broad, sandy shelf largely does not provide the firm foundation needed for the development of reef communities to support recreational and commercial fish species including grouper, snapper, black sea bass and amberjack.

“Natural and artificial reef habitats are important to Georgia fisheries because they provide hard, permanent structure on the Georgia shelf, which is dominantly a vast underwater desert of shifting sands,” said Clark Alexander, professor and director of the University of Georgia Skidaway Institute of Oceanography. “The Georgia Department of Natural Resources has invested significantly over the past several years in developing the capacity to map these areas to enhance the management of these reef communities.“

To increase the availability of high-quality hard bottom areas off Georgia, the DNR began an artificial reef-building program in 1971 to deploy materials at various locations across the continental shelf, from 2 to 30 miles offshore. Reef materials include concrete slabs and culverts from road, bridge and building demolition, subway cars, ships, barges, and U.S. Army tanks. Because some of these reefs are far offshore and DNR resources are limited, the status of some of that material has not been examined for decades.

For the past five years, Alexander has been leading an effort to improve understanding of marine, coastal and estuarine habitats and functions using high-resolution sonar to map state water bottoms, with funding from the DNR Coastal Incentive Grant program. Alexander’s team has amassed critical depth and habitat information for five of Georgia’s sounds (Wassaw, Ossabaw, St. Catherine’s, Doboy and Sapelo), revealing deeply scoured areas where underwater cliffs have formed to create hard substrate where complex ecosystems and biological communities have developed.

“These inshore, hardbottom habitats should enhance biodiversity in the areas near these structures and enhance ecosystems supporting both commercial and recreational species across the continental shelf,” Alexander said.

Alexander is currently leading a new, three-year project mapping important fish habitats in state waters — the newly discovered estuarine habitats, and artificial reef structures within 10 nautical miles of shore – those areas most accessible to recreational anglers, boaters and divers. In addition, his research group is mapping previously unmapped portions of the sounds and tidal rivers deeper than 15 meters to discover the extent of these newly identified estuarine hardbottom habitats.

Skidaway Institute researchers will work with DNR to update the online “Boater’s Guide to Artificial Reefs” with accurate locations and imagery of deployed materials for these reefs. These new, more accurate artificial reef surveys will also document recent changes in the locations and integrity of placed materials and verify the low-tide water depths over all features in the artificial reefs to enhance navigational safety.

Despite COVID-19 delays, UGA Skidaway Institute scientist heading home from the Arctic

After four months at sea, including two and a half months on board a German ice breaker locked in the Arctic ice cap, University of Georgia Skidaway Institute of Oceanography scientist Chris Marsay is on his way home. His return trip comes six weeks later than planned due to travel restrictions imposed by the COVID-19 crisis.

Chris Marsay, all wrapped up for working out on the ice during windy conditions.

Marsay has been on board the research vessel Polarstern as part of a major international research project to study climate change in the Arctic named Multidisciplinary drifting Observatory for the Study of Arctic Climate, or “MOSAiC.” Last fall the Polarstern sailed into the Arctic Ocean until it became locked in the ice. The plan was for the ship to drift with the ice for a year all the while serving as a headquarters for scientists to study Arctic climate change. Scientists were scheduled in shifts or “legs” to work for two to three months at a time. However, unable to exchange the science teams by either air or with another ice breaker, MOSAiC organizers decided to pull the Polarstern out of the ice pack and leave the research station for an estimated three weeks while the changeover takes place.

“My time working at the MOSAiC ice floe has come to an end, and I am currently traveling south on the Polarstern towards Svalbard where the exchange between personnel from legs three and four of the project will take place,” Marsay said. “Due to the travel restrictions in place because of COVID-19, it was not possible to carry out the exchange at the ice floe itself as originally planned.”

The replacement team is already at Svalbard aboard two other German vessels. They completed a two-week quarantine and multiple coronavirus tests before departure. The teams will exchange ship-to-ship in a fiord since Svalbard, a Norwegian archipelago, is closed to outside visitors because of COVID-19.

According to Marsay, his time at the MOSAiC ice floe has been eventful. “The ice was much more dynamic than it had been during the first months of the MOSAiC project,” he said. “Cracks and leads frequently opened up in the area around the ship, and the ice movement also formed ridges of ice blocks several feet high.”

Ice Crack 650p

A crack that opened up next to the ship in mid-March meant that some equipment had to be hurriedly moved to safety.

All of these events restricted access to some research sites, but the work continued, providing new sampling opportunities for the researchers.

This was not Marsay’s first trip to the Arctic. A 2015 research cruise took him to the North Pole, but this trip was a new experience. “It’s been unique to witness the transition from winter to spring in the central Arctic Ocean,” he said. “During our time at the floe we experienced a minimum temperature of negative 40 degrees Celsius, not accounting for wind chill, and a maximum of zero degrees Celsius. The sun did not rise until two weeks after we arrived at the floe, and has not set since late March.”

Marsay also experienced windy days with storm-force winds and whiteout conditions due to blowing snow, and days with beautiful clear skies when the sun reflecting off the snow was dazzling, he said.

Ship Blown Snow 650p

As calm conditions gradually return after a couple of days of windy conditions, Polarstern is visible through some blowing snow at ground level.

During his participation in MOSAiC, Marsay collected snow, ice cores, sea water and aerosol samples as part of our project studying the atmospheric deposition of trace elements in the central Arctic.

SkiDoo 600p

Each Monday, Marsay was part of a team that collected multiple ice cores at a site far enough away from the ship that a Ski-Doo and sledges were needed.

He also learned some new skills, including driving a Ski-Doo, and on several occasions he carried a rifle and served as a polar bear guard for colleagues.

Bear Tracks 480p

The researches had one polar bear visit (that they know of) during leg 3. These footprints within a couple of hundred yards of Polarstern.

“We on board will have been at sea for over four months by the time we get to Germany,” Marsay said. “When we started, the COVID 19 virus was not widespread outside of China.

“We have all been following the news from back home, and although we’re looking forward to getting home, everyone is expecting some initial difficulties getting used to the way that public life has changed while we’ve been away.”

UGA Skidaway campus reacts to COVID-19 crisis

Like everyone else in the country, the organizations on the UGA Skidaway Marine Science Campus have been affected by the COVID-19 pandemic.

In mid-March, UGA Skidaway Institute cut back on all on-campus activities. Most active research was put on hold and faculty and staff were directed to telecommute as possible. Scheduled research and educational cruises on board the R/V Savannah were postponed. A small team of staff members continue to work on campus to maintain facilities and systems. Monthly Evening @ Skidaway public programs are cancelled, at least through the summer.

“Although we are currently pausing our research and educational efforts, we are eager to restart those programs as soon as it is safe to do so,” Director Clark Alexander said.

UGA Marine Extension and Georgia Sea Grant shut down operations about the same time. The UGA Aquarium closed, and all educational field trips were cancelled for the remainder of the school year.

“Our biggest priorities in our response has been the health and safety of our staff and the public that we interact with regularly,” Mark Risse, director of Marine Extension and Georgia Sea Grant said. “For this reason, we made the hard decision to cancel many of our public programs and conferences this spring, as well as our summer marine science camps scheduled in June and July.”

Educators at the UGA Aquarium have transitioned several in-person public programs to virtual platforms. Registration is currently open for a series of engaging online events scheduled for June and July that focus on marine animals and coastal habitats. Learn more at gacoast.uga.edu/events.

Marine Extension and Georgia Sea Grant’s Shellfish Research Lab is supporting the aquaculture industry by providing technical assistance to shellfish growers and sharing information about COVID-related resources. A handful of extension specialists at the lab continue to keep the oyster hatchery running and are producing oyster seed for shellfish farmers on the coast.

Gray’s Reef National Marine Sanctuary remains open while its headquarters facilities on the UGA Skidaway Marine Science Campus are closed and staff is working from home. Most non-essential operations and research activities have been postponed, including the annual NOAA Ship Nancy Foster expedition, typically hosted in mid-July. The Gray’s Reef Expo on River Street has been tentatively rescheduled for November 21-22. Outreach from Gray’s Reef is focusing on digital and virtual events. Updates and additional news from the sanctuary be found at Gray’s Reef’s social media pages. This includes facebook.com/GraysReefSanctuaryor twitter.com/GraysReefNMS.

Former UGA Skidaway Institute director Jim Sanders retires

Former UGA Skidaway Institute executive director Jim Sanders retired last summer. Sanders led the institution from 2001 until 2016, when he stepped back from his executive directorship, but remained active in a faculty post. During his 15 years as director or executive director, Sanders guided Skidaway Institute through two recessions and the 2013 merger with the University of Georgia.

Sanders earned his bachelor’s degree in zoology from Duke University and followed it up with a master’s degree and doctorate in marine sciences from the University of North Carolina – Chapel Hill. His first exposure to Skidaway Institute came as a graduate student with Herb Windom in the 1970s.

Prior to his arrival in Savannah in 2001, Sanders was on the faculty and served as director of the Academy of Natural Sciences’ Estuarine Research Center in Maryland. He then was chairman of the Department of Ocean, Earth and Atmospheric Sciences at Old Dominion University in Virginia.

Sanders is known for his interests within the area of nutrient and trace element biogeochemistry, especially how trace elements are transported through coastal zones, transformed by chemical and biological reactions during transport, and how they influence growth and species composition of autotrophic organisms.

Sanders has been very active as a consultant to federal and state science agencies, and industrial groups in the U.S. and Europe. He is a member of numerous scientific societies, was president of the National Association of Marine Laboratories, and was a trustee and officer of the Consortium for Ocean Leadership. He is the author of over 75 scientific publications.

Shortly after taking the helm at Skidaway Institute, the nation was hit with an economic downturn sparked by the 9/11 terrorist attacks, and maintaining adequate funding for research and operations was a challenge.

“The most effective way to deal with it was to hire innovative and interdisciplinary faculty members who would come up with important research questions and then find funding to pursue those avenues,” Sanders said.

Looking back, Sanders said he has always been amazed at the extent to which Skidaway Institute fosters an interactive, collegial work experience.

“I have been at a number of other institutions, large and small, many with a similar focus on oceanography, but I have never felt the interconnections that Skidaway has offered, both to me and other staff, over the past 42 years,” Sanders said.

As Sanders looks back over his time at Skidaway, he is most proud for what he, the faculty and staff have done together.

“In the end, I measure my success through my colleagues and our interactions,” he said. “Really, my career has not been defined by the grants written, or the publications, or even the research that I have performed, but that I was in a position to help others achieve their goals, and perhaps even reach a bit higher in some cases.”

Sanders remains at the institute as a professor emeritus.

Ohnemus joins UGA Skidaway Institute faculty

Chemical oceanographer Daniel Ohnemus has joined the faculty of UGA Skidaway Institute of Oceanography and the UGA Department of Marine Sciences as an assistant professor.

Ohnemus received his bachelor’s degree from Williams College and his Ph.D. in chemical oceanography from the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution Joint Program. He joined UGA Skidaway Institute following a postdoctoral appointment at Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine.

Ohnemus’ research focuses on marine particles—the mixture of living organisms and non-living chemicals that transport and transform material within the oceans.

“All living organisms need small ‘trace’ amounts of elements like iron and copper to live,” Ohnemus said. “Unlike on land where plants can get these elements from soil, algae in the oceans have to get them from much rarer things like dust, other cells or seawater itself. The limited availability of these elements is an important control on many marine ecosystems.”

The son of a lobsterman and an elementary school educator, Ohnemus grew up on Cape Cod and became fascinated with the ocean at a young age. In fourth grade, his class visited Woods Hole to take part in a satellite video call with marine scientists off the Galapagos Islands. Seeing underwater robots explore a coral reef got Ohnemus hooked on marine science.

At Williams College, he pursued a double major in biology and chemistry. After graduation, he returned to Woods Hole, first as a research technician and later as a graduate student. After earning his Ph.D., he completed a postdoctoral appointment at the Bigelow Laboratory for Ocean Sciences, continuing to concentrate on marine particles and trace elements.

The Roebling barn in perspective

by Debbie Jahnke

Editor’s notes: Debbie and Rick Jahnke were longtime members of the Skidaway Institute family. Rick was a faculty scientist and, for several months, interim director of the institute. Debbie was his research coordinator. They both retired in 2008 and moved to Port Townsend, Washington.

 In March of this year, the Georgia General Assembly approved a $3 million bond issue to renovate and repurpose the old Roebling cattle show barn at UGA Skidaway Institute into usable laboratory and meeting space.

In 1986, Rick Jahnke interviewed for a faculty position at Skidaway Institute of Oceanography. At the time, he was a research scientist at Scripps Institution of Oceanography. Rick returned home to San Diego with the impression that he wouldn’t be hired because Stuart Wakeham had also interviewed for the position and would undoubtedly be selected. Instead, Skidaway Institute came up with the funds for two positions and hired both Rick and Stuart.

Rick’s start-up requests to Skidaway Institute were modest: a germanium detector and a desktop computer. He also requested lab and office space in the Roebling building and a staging lab in the barn for maintenance, repair and modification of his various seagoing autonomous vehicles. The barn was nearly perfect for that purpose, with plenty of storage space and a central open area that allowed loading and offloading of equipment with a hand-winched pulley system.OLYMPUS DIGITAL CAMERA

Rick didn’t need any extra space for me and, instead, split his office with a wall so there was a spot just big enough for my desk and a “labradog” named Daisy. I was the analytical tech for his research and he hired an equipment tech for the seagoing operations. The barn lab operations expanded to the second floor of the barn when it became clear that anyone interested in measuring natural levels of C-14 wasn’t going to be able to do it in many existing Skidaway Institute labs. In the free-form early days of productivity measurements, enough C-14 made it into the ambient spaces of many Skidaway Institute labs that C-14 dating indicated that our labs existed about 50,000 years in the future. The levels of so-called contamination were in no way concerning for health or safety, but they made natural abundance measurements impossible without a “clean” space for sample storage. The bright yellow room with the pink and green interior and cold room on the second floor of the barn were the result.

From those barn labs, autonomous vehicles were staged, packed and deployed for oceanographic research off western Africa, Peru, Panama, New Guinea, deep shelves off Cape Hatteras, California, Oregon and other locations, as well as the Georgia shelf. Samples were returned and stored in the yellow lab upstairs.

The barn provided another opportunity for me when I was drafted in a weak moment to try to improve what was quite dismal visitor housing at Skidaway Institute in the 1980s. The first housing we made habitable was the barn apartment. As we worked through the process of getting three NSF grants for housing, we also were able to set up a small laundry room in the barn so that volunteers could keep clean linens in the housing we did have. The first successful grant built the quadraplex (Menzel, Zeigler, Carpenter and Knight apartments). The second grant rehabilitated the housing that existed since the plantation days (the barn apartment, now renamed Baggett, Rice House, Thomas and Martin apartments). The third grant built the Commons. I spent many hours in that barn laundry room while most of my weekends and holidays were spent cleaning housing units before the institute finally figured out how to pay someone to do that as a real job.

Rick and I retired in 2008 and headed west with our five cats. All I know of the modern Skidaway Institute is what I read on the website and Facebook pages and occasional emails from friends still there. Skidaway was wonderful to us and the barn was a big part of the ease with which our research was facilitated. It was with considerable pleasure that we learned of the grand and useful future being planned for the good old barn.
